Fuel system status OL Fault and CL Fault - A solution

Been tuning a 2012 Challenger for the past few weeks, making baby step progress, and bought the book package from The Tuning School. Had an issue with the fuel system not being "normal" in scanner. I found the GM related solution which is of no help because of differences in tables. Nothing useful in the Misfire tab. Looked at a spark plug, looks fine. Scratched my head and quickly found Fuel>O2>ECT Rear and set it to max of 376 degrees F. Problem solved. Reset adaptives like usual after EVERY flash and it is behaving quite nicely now. Reason for the error is because I removed rear o2 bank 1 to insert the aem wideband into. I hope this information can be of use to someone. And hopefully we're all paying attention to our scanner in detail.

Still wondering....How come I must stop a log, save it, then reopen it for the entire fuel mass graph (Eq ratio error) to populate from the run I just performed? Else just a few labels will populate. Cheers.
